Question

What is the slope of the line that contains the points (-1,2) (4,3)

Answer 1

`\bf (\stackrel{x_1}{-1}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{3}) \\\\\\ % slope = m slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{3-2}{4-(-1)}\implies \cfrac{3-2}{4+1}\implies \cfrac{1}{5}`
